Synopsis: An unusual epidemic breaks out inflicting children and adults alike, while its cure evades discovery even by expert Healers.

Finally it comes to light that Voldemort's preceding silence wasn't a coincidence; he caused the epidemic himself, thus declaring war on the entire wizarding society. All those who proclaim their loyalty to Voldemort are provided with a protective serum, making them immune to the disease.

However, as all plans, this one has its failings, too. The serum progressively loses its potency, and people who receive it eventually become sick as well. But there is one person unaffected by the illness. Professor Snape remains clueless as to why Harry Potter, the only person who was present when the first disease case emerged, still remains completely healthy…

The race against time commences, even as Harry's protection becomes a challenge. Everyone wants to capture him, seeing that his blood may hold the answer to saving the wizarding world…
